COMBINED JACK AND TRUCK.-

Specification of Lettera Patent. Patented Aug. 23, 1910.

Application led April 14, 1909. Serial No. 489,923.

To all wlw/m it may concern:

Be it known that I, WILLIAM BECKERT, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania., have invented certain new and useful Improvements in Combined Jacks and Trucks, of which the following is a specification.

My invention relates to an improvement in combined jacks and trucks, and relates more particularly to the ty e of device disclosed in Letters Patent, lso. 386,913, and No.493,8l1,granted to me July 31, 1888 and March 21. 1893', respectively, the especial object of the present improvement being to provide and adapt a truck for low-wheeled vehicles, such as automobiles the axles of many of which are not over` nine and a half inches from the ground.

In the accompanying drawings -Figure 1 is a view in perspective, and Fig. 2 is an enlarged sectional view through one of the jacks, on line 2 2 of Fig. 1, which is in a plane coincident with the center of tube 1.

In my present invention, the frame is adjustable as to length and width, and adapted' to support both axles, it being preferably made of the telescopic tubular sides 1, l, and ends- 2, 2. These are screwed into the side outlet tees 3, 3, which constitute the corners of the frame.

The numeral 5 represents a caster frame which comprises a ollow center, and the side leaves 6, 6, having orifices 7 7, therein, between which the caster wheels 8, 8, are placed, they being supported onl the common journal 9 which 1s held in place by a nut 10 screwed on the end thereof. 'lhe caster frame is loosel mounted on a hollow or tubular post 11, t e upper end of which is screwed into the lower end of the tee, where it is held by a lock nut 12 screwed on the lower end of the hollow ost.

A screwfjack 13 turns In the internal threads 14 of the polygonal head 15, which head really constitutes an extension of the corner tee and post, the entire construction being hollow from top to bottom, this. being a feature of the invention, and admitting of vthe screw jack being screwed down to' the floor to get it to the lowest possible point to accommodate the lowest possible axle.

16 at the top toreceive and sup ort the axle, as the jack 1s adjustedu and d the vehicle' from the oor, and to throw its weight upon the truck.

From the foregoing it will be seen that I have provided a combined jack and truck for the support of both front l'and rear axle, the parts of which are mounted at a minimum elevation from the floor, so that the device may be run beneath the axles and adjusted as tolength and width, and the jacksA lowered sufficiently to clear the lowest -axle in placin the truck, after which they are raised to lift the wheels ofthe vehicle from the ground or loor to support the vehicle gear suiiiciently high 1to receive the wheels.v

Having fully described my invention, what I claim as `'new and desire to secure by Letters Patent, is

. 1. A device of the character described, the frame of which comprises sides, ends, and outlet tees which connectsaid sides and ends toggethe'r and form the corners of the frame. a ead surmounting each tee, the bores of which are screw-threaded, and screw-jacks. the threads of which turn in the threads or" the heads, a caster frame rotatably connected witheach tee, and each caster frame provided with leaves which extend laterally, and journals extending through the leaves at one side of the caster frame and out of the aths of the screw-jacks, and a caster whee mounted on each journal whereby each screw may be lowered to a point below the axle of the adjacent caster-wheel.

2. A screw jack for rolling trucks com-` y WM. BECKERT.
